I have not seen the season of Project Greenlight that covered the making of this film, so I might ask questions already answered by the documentary. However, surely some of the message board members have seen it and could help steer us away from duplicates. Hashing out the questions by group consensus is definitely a good idea.

Sounds neat ASHTHECAT. Hope you get the interview. Instead of particulars about the movie you should ask about her movie career like:

How did she get started in film?

What was her first film?

What was her first big break?

How did she like making the movie Feast?

What are her future roles?

Basically ask her a lot a questions about her and not so much about the movie. Make the movie secondary in your approach. Focus on her career and interest. It might interest her when you ask her for an interview.
